  WERF Research Helps Cincinnati Use Innovative Biomarkers To Assess & Monitor Water Quality In National Scenic River

  In 1986, ambient water quality criteria recommendations from the USEPA were developed for recreational waters using E. coli as an indicator organism. With the benefit of advances in environmental microbiology, molecular tools and quantitative microbial risk assessment (QMRA), USEPA has released the recreational water quality criteria (RWQC) recommendations that reflect the risk to human health from fecal contamination.

  Seattle Public Utilities Case Study: Using A Business Case Evaluation To Identify The Most Desirable Rehabilitation Outcome

  A recently published WERF report, Flood Grouting for Infiltration Reduction on Private Side Sewers (INFR5R11) provides results of a field test of the flood grouting process to seal laterals, sewer mains, and manholes. Prior to obtaining approval to proceed with this pilot project, a “business case” was prepared to compare the total life-cycle cost of the proposed option to other alternatives, which included joint grouting, pipe bursting, cast-in-place pipe (CIPP) lining, and replacement with upsized pipe. The amount of flow reduction was measured and compared that to the total project costs as tracked through Seattle Public Utilities’ cost accounting system. Researchers looked at the potential for using the technology to reduce the risk for future backups in Seattle’s Broadview neighborhood, as well as its applicability in other locations.

• Advanced Pump Design Enhances Performance, Thrills Customers

  With lift stations set among households and a pristine lake, failure is not an option for the Valley Rural Utility Company in Lawrenceburg, IN. The old lift stations were costing up to $30,000/year to maintain, due to poor design and persistent clogging. A new Flygt N-Pump has changed the utility’s course, however, proving with one (easy) installation the cost savings that can be gained through advanced impeller technology and remote SCADA operability.
